"Monkeys can climb Crickets can leap Horses can race Owls can seek Cheetahs can run Eagles can fly People can try But that's about it."

Natsuki appears to be a brash, blunt, cranky, and seemingly arrogant girl at first, with a cute, softer interior as a result of insecurity, convincing Monika enough to class her as the embodiment of a tsundere. While she is impulsive and can speak without thinking, Natsuki truly cares about her friends and, even when she has obvious anger issues, doesn't enjoy fights or arguments with people.

Otaku Trivia:

1) Natsuki prefers to stay at the Literature Club than her home and is visibly worried about fading into the background if more people were to join the club.

2) Natsuki fears what would happen if her father spots her reading "childish" manga.

3) Natsuki's version of "Okay, Everyone!" involves a much simpler tune consisting of a recorder xylophone duet, though it is slightly off-tempo, representing her childish and simplistic nature.
